    I connected one relay that actually controls fuel pump to FC pin
    and another relay to fool ECU to FPR pin
    nothing more related to fuel pump

    doesnt matter if throttle works on now
    its just that the ecu controls the fbw
    anyway i cant tell u if running cable throttle on fbw ecu works
    ive never had to dodgey it up like that
    maybe others can help from here

    yes that's a resistor you don't need it. Just one relay for real and one to fool ecu

    Its not like the fuel pump is turning off its more like the ecu shuts down the engine when its on high boost

    Would be a good idea to wire up the fuel pump relay as in the wiring diagram and get rid of that 78 code. The ecu expects to see that relay

    id be more worried about fbw setup than code 78
    ive never seen that cause problems

    also have u tried running low boost
    stop wirrying bout the stupid things liek fuel pump and air flow
    if its a hi boost problem drop the boost

    Yeah sounds like a good idea but how can I lower the boost on the turbo ........ And what does everyone think about a stand alone computer for a daily?
